The prognostic value of 11 Japanese classification and 8 AJCC staging systems in Chinese patients with esophageal squamous cell carcinoma.

Background: Two staging systems, the 8th staging system by the American Joint Committee on Cancer (AJCC) and the 11th Japanese classification by Japan Esophageal Society (JES), are currently applied in the clinic for predicting the prognosis of patients with esophageal squamous cell carcinoma (ESCC). The differences between the two staging systems have been widely researched. However, little studies focus on the differences in specific staging between the two systems.

Combined model of radiomics and clinical features for differentiating pneumonic-type mucinous adenocarcinoma from lobar pneumonia: An exploratory study.

Purpose: The purpose of this study was to distinguish pneumonic-type mucinous adenocarcinoma (PTMA) from lobar pneumonia (LP) by pre-treatment CT radiological and clinical or radiological parameters.

Methods: A total of 199 patients (patients diagnosed with LP = 138, patients diagnosed with PTMA = 61) were retrospectively evaluated and assigned to either the training cohort ( = 140) or the validation cohort ( = 59). Radiomics features were extracted from chest CT plain images.

Pretreatment Thoracic CT Radiomic Features to Predict Brain Metastases in Patients With -Rearranged Non-Small Cell Lung Cancer.

To identify CT imaging biomarkers based on radiomic features for predicting brain metastases (BM) in patients with -rearranged non-small cell lung cancer (NSCLC). NSCLC patients with pathologically confirmed rearrangement from January 2014 to December 2020 in our hospital were enrolled retrospectively in this study. Finally, 77 patients were included according to the inclusion and exclusion criteria.

Risk stratification in GIST: shape quantification with CT is a predictive factor.

Background: Tumor shape is strongly associated with some tumor's genomic subtypes and patient outcomes. Our purpose is to find the relationship between risk stratification and the shape of GISTs.

Methods: A total of 101 patients with primary GISTs were confirmed by pathology and immunohistochemistry and underwent enhanced CT examination.

Malignant jejunal gastrointestinal stromal tumor with history of prostate cancer: A case report.

Rationale: The problem of the coexistence of gastrointestinal stromal tumor (GIST) with other neoplasms is complex, and carcinomas of prostate is one of the common types of GIST-associated cancers. Doubling time of GIST is about 3.9 months for high-risk GIST, and the treatment paradigm for GIST has required the integration of surgery and molecular therapy.

False-positive diagnosis of disease progression by magnetic resonance imaging for response assessment in prostate cancer with bone metastases: A case report and review of the pitfalls of images in the literature.

Bone metastases are common in prostate cancer. However, differentiating neoplastic from non-neoplastic alterations of bone on images is challenging. In the present report, a rare case of bone marrow reconversion on magnetic resonance imaging (MRI) assessment, which may lead to a false-positive diagnosis of disease progression of bone metastases in hormone-resistant prostate cancer, is presented.

Concurrent involved-field radiotherapy and XELOX versus XELOX chemotherapy alone in gastric cancer patients with postoperative locoregional recurrence.

Purpose: To compare the treatment outcomes of concurrent involved-field radiotherapy and XELOX (oxaliplatin and capecitabine) versus XELOX chemotherapy alone in gastric adenocarcinoma patients with locoregional recurrence.

Materials And Methods: From 2004 to 2008, 79 patients with recurrent locoregional gastric cancer after curative resection of gastric tumor were enrolled. Among them, 41 patients received involved-field radiotherapy (median dose 50 Gy) by a 3-dimensional conformal radiotherapy technique and concurrent XELOX chemotherapy, and 38 patients were treated with XELOX chemotherapy alone (oxaliplatin 130 mg/m, capecitabine 1000 mg/m, twice daily, 3 wk each cycle).

A comparative proteomic study identified calreticulin and prohibitin up-regulated in adrenocortical carcinomas.

Background: Identifying novel tumor biomarkers to develop more effective diagnostic and therapeutic strategies for patients with ACC is urgently needed. The aim of the study was to compare the proteomic profiles between adrenocortical carcinomas (ACC) and normal adrenocortical tissues in order to identify novel potential biomarkers for ACC.

Methods: The protein samples from 12 ACC tissues and their paired adjacent normal adrenocortical tissues were profiled with two-dimensional electrophoresis; and differentially expressed proteins were identified by mass spectrometry.

Polymorphisms of interleukin-10 promoter are not associated with prognosis of advanced gastric cancer.

Aim: To evaluate the association between of the interleukin-10 (IL-10) promoter polymorphisms and survival of advanced gastric cancer (GC) patients.

Methods: The IL-10 (-1082, rs1800896; -819, rs1800871; and-592, rs1800896) genotypes in 234 patients with advanced gastric cancer and in 243 healthy controls were determined by polymerase chain reaction-restriction fragment length polymorphism assay. Odds ratios (OR) and 95% confidence intervals (CI) were calculated by unconditional logistic regression for the associations between IL-10 genotypes and the risk of GC.

[Development and applications of the extracorporeal control point module on multi-mode medical images].

This paper introduces a display module which can be used on multi-mode medical images. The module has a small size and can be easily used for point-selecting puncture diagnosis and treatment, and registration for image fusion control points.

[CT and MRI image fusion in three-dimensional conformal radiotherapy for cranial carcinoma].

Objective: To investigate the advantage of CT and MRI image fusion in determining the target precisely during 3-dimensional conformal radiotherapy for cranial carcinoma.

Methods: Twenty-five patients received CT and MRI examination simultaneously for localizing the tumor and defining target before 3-dimensional conformal radiotherapy. The target defined by MRI image was used as gross tumor volume, whereas CT value was used to calculate dose, making plan for radiotherapy.
